Proton Therapy vs. X-rays
Radiation therapy with X-rays is a valuable treatment option for many cancers but its role is
limited by the risk of damage to organs adjacent to the tumor site that can sometimes be life
threatening. This is because X-rays are highly penetrating, imparting ionizing energy to cells as
they pass through the skin and tissues. This is not always a limiting factor: in the case of prostate
cancer, for example, treatment options include radical prostatectomy, standard radiation therapy
and proton therapy.
While X-ray delivers radiation not only to the tumor but also to healthy organs and tissues
surrounding the tumor, proton beams can release its maximum energy at the tumor. It attacks
DNA in the core of the cancer cells, making the cancer cells unable to reproduce which then
followed by a gradual disappearance of the tumor. Proton therapy is often considered the most
advanced form of radiation available today. It results in less radiation, dramatically minimizes
serious side effects and lowers the chances of secondary cancers.
Why Proton Therapy
Unlike standard radiation or surgery, proton therapy is an extremely precise form of treatment for
certain cancers. Proton beams are a flow of particles generated from hydrogen gas. By using an
accelerator, a synchrotron accelerating these particles to near the speed of light, making it able to
precisely target cancer. With that said, proton beams have the ability to focus and affect cancer
lesions with minimal impact on surrounding muscle and tissues, thus minimizes detrimental side
effects on healthy tissues.
Benefits of Proton Therapy
- Unmatched Precision - Proton beams can target the tumor and inflict damage on cancer cells.
- Reduced Side Effects - Precision treatment minimizes serious side effects
- Suitable for Complex Conditions - Prostate, lung, liver, bile duct, pancreas, head and neck, esophagus, breast and
- Lower Chances of Secondary Tumors - Reduces the risk of radiation-induced secondary cancers
